Properties

Private _content

Private _source

_source: any

Private _trans

_trans: any

Readonly dataset

dataset: DOMStringMap

The dataset for the widget's DOM node.

Readonly disposed

disposed: ISignal<this, void>

A signal emitted when the widget is disposed.

id

id: string

Set the id of the widget's DOM node.

Readonly isAttached

isAttached: boolean

Test whether the widget's node is attached to the DOM.

Readonly isDisposed

isDisposed: boolean

Test whether the widget has been disposed.

Readonly isHidden

isHidden: boolean

Test whether the widget is explicitly hidden.

Readonly isVisible

isVisible: boolean

Test whether the widget is visible.

Notes

A widget is visible when it is attached to the DOM, is not explicitly hidden, and has no explicitly hidden ancestors.

layout

layout: Layout | null

Set the layout for the widget.

Notes

The layout is single-use only. It cannot be changed after the first assignment.

The layout is disposed automatically when the widget is disposed.

Readonly node

node: HTMLElement

Get the DOM node owned by the widget.

parent

parent: Widget | null

Set the parent of the widget.

Notes

Children are typically added to a widget by using a layout, which means user code will not normally set the parent widget directly.

The widget will be automatically removed from its old parent.

This is a no-op if there is no effective parent change.

Readonly title

title: Title<Widget>

The title object for the widget.

Notes

The title object is used by some container widgets when displaying the widget alongside some title, such as a tab panel or side bar.

Since not all widgets will use the title, it is created on demand.

The owner property of the title is set to this widget.

Protected translator

translator: ITranslator

Readonly widgets

widgets: ReadonlyArray<Widget>

A read-only array of the widgets in the panel.

Private Static _generateContentWidget

_generateContentWidget: any
